Nursing Leadership and Management
1. Functional nursing has some advantages, which one is an EXCEPTION?
- A. Psychological and sociological needs are emphasized.
- B. Great control of work activities.
- C. Most economical way of delivering nursing services.
- D. Workers feel secure in dependent role
Correct answer: B
Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.
2. What does "monophyletic" mean in the context of classification?
- A. A group with a single representative organism
- B. A group with diverse and unrelated members
- C. A group with similar functions but different origins
- D. A group descended from a common ancestor
Correct answer: D
Rationale: Rationale: In the context of classification, "monophyletic" refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term "monophyletic" in the context of classification.
3. Which of these organs is NOT involved in the production of digestive enzymes?
- A. Mouth
- B. Stomach
- C. Pancreas
- D. Small intestine
Correct answer: A
Rationale: Rationale: A) Mouth: The mouth is involved in the mechanical breakdown of food through chewing and the initiation of carbohydrate digestion by the enzyme amylase in saliva, but it does not produce digestive enzymes. B) Stomach: The stomach produces gastric juices containing enzymes like pepsin that help break down proteins. C) Pancreas: The pancreas produces various digestive enzymes such as amylase, lipase, and proteases that aid in the digestion of carbohydrates, fats, and proteins. D) Small intestine: The small intestine produces enzymes such as peptidases, sucrase, lactase, and maltase that further break down proteins, carbohydrates, and fats for absorption. Therefore, the mouth is the organ that is NOT involved in the production of digestive enzymes.
4. Which type of RNA carries the genetic code from DNA to ribosomes?
- A. Ribosomal RNA (rRNA)
- B. Transfer RNA (tRNA)
- C. Messenger RNA (mRNA)
- D. Deoxyribonucleic acid (DNA)
Correct answer: C
Rationale: Rationale: - Messenger RNA (mRNA) carries the genetic information from DNA in the cell's nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs. - Ribosomal RNA (rRNA) is a component of the ribosomes where protein synthesis takes place. - Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosomes during protein synthesis. - Deoxyribonucleic acid (DNA) is the genetic material that contains the instructions for building and maintaining an organism. DNA is transcribed into mRNA before being translated into proteins.
5. The ball-and-socket joint, which allows for wide range of motion, is found in the connection between:
- A. Upper arm and shoulder blade (scapula)
- B. Collarbone (clavicle) and breastbone (sternum)
- C. Two vertebrae in the spine
- D. Ribs and sternum
Correct answer: A
Rationale: The correct answer is A: 'Upper arm and shoulder blade (scapula).' The ball-and-socket joint is found in the connection between the humerus (upper arm bone) and the scapula (shoulder blade). This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. The collarbone (clavicle) and breastbone (sternum) are connected by a cartilaginous joint, not a ball-and-socket joint. Two vertebrae in the spine are connected by facet joints, and the ribs and sternum are connected by cartilaginous joints and the costovertebral joints. Therefore, the ball-and-socket joint is uniquely found in the connection between the upper arm and the shoulder blade, allowing for the shoulder's impressive range of motion.
6. Which sentence uses the colon correctly?
- A. I brought snacks: chips, salsa, and guacamole.
- B. The winner is: Sarah!
- C. He loves all things chocolate: cake, ice cream, and candy bars.
- D. Please bring the following items: pen, paper, and stapler.
Correct answer: A
Rationale: Colons are used to introduce a list or explanation that follows an independent clause. Options (a) and (c) use the colon correctly.
